PHOTOGRAPHlC-PRINTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 478,663, dated July 12, 1892. Application filed July 17, 1891. Serial No. 399,819. (No model.)

To all whom it may concern..-

Be it known that I, JOHN URIE, Jr., a subject of the Queen of Great Britain, residing at Jersey City, Hudson county, New Jersey, have invented certain new and useful Improvements in Photographic-Printing Machines, fully described and representedin the following specification and the accompanying drawings, forming a part of the same.

This invention relates to a machine for making manysuccessive prints from a single negative upon a continuous web of sensitized paper; and comprises a printing-frame for holding the negative, a supply-roll for the sensitized paper, a take-up roll for the same, and means for actuatingthe said members intermittingly.

The invention consists partly in a special construction of the take-up roll and means for actuating it, partly in a special mechanism for operating a platen to press the sensitized paper against the negative during the printing operation, and partly in means for controlling the light employed in the printing operation.

In the annexed drawings, Figure l is a side elevation of the machine, and Fig. 2 a plan of the same with a box containing the lighting apparatus and the web of sensitized paper removed. Fig. 3 is a side view, and Fig. 4 an edge view, of an electric switch for controlling the light.

A is the main frame of the machine, having the main shaft S journaled therein and provided with the fast and loose pulleys P and P to receivethe power required to drive the machine.

a is a rectangular printing-frame, having the glass plate g secured within the same, to which latter is secured along its edges the negative plate a by cement or other suitable means.

A box Z), having a row of incandescent lamps upon each of its four sides, is fitted within the printing-frame, the glass plate 9 serving at its bottom and permitting thelight therefrom to pass through the negative n to the web '20 of sensitized paper where exposed thereto under the frame. A platen p, which would in practice be covered with a suitable pad of soft material,is applied under the web w to press the same upward against the film side of the negative. This platen is mounted, by means of a ball-ad-soekent connection 0; upon a stud (Z, held adjustable vertically by means of the set-screw e in a socket in the laterally-projecting arm of a bell-crank f, pivoted upon the tie-rod T of the frame A. The platen p is pressed normally upward by means of the weight IV upon the laterally-projecting arm of the bell-crank h, the upwardlyprojecting arm of which is connected by the link 2' with the depending arm of the bellcrankf, the tension thus produced upon the link i causing a corresponding upward pressure of the lateral arm of the bell-crankf. The flexible joint formed by the ball-andsocket connection 0 permits the platen to adjust itself against the negative and interposed web 10, and thus distributes equally the upward pressure applied by the bell-crank.

The main shaft 5 is provided adjacent to the depending arm of. the bell-crank f with an adjustable cam j, having segmental faces engaging the end of the said depending arm or an anti-friction roller j" upon the same. The cam j is formed of two similar flat plates having concentric slots j and bolts j to clamp the plates together. The end of the depending arm or its anti-friction roller is made of sufficient width to bear against either or both of said parts of the divided cam, and the circular adjustment of the latter upon each other operates to vary the operative face of the cam presented, and to thus correspondingly vary the period the platen remains depressed by means of the action of the said cam upon the bell-crank f.

The supply-roller is mounted in open sockets .5" in the frame of the machine and is provided, as shown in dotted lines in Fig. 1, with a roll of sensitized paper in readiness for the printing operation. In order to prevent the unrolling of the paper too rapidly, a brakeroller is applied thereto. This brake-roller consists of a heavy cylinder 5 of metal of the same width as the supply-roller, having hubs s at both ends of nearly the same diameter as the body of the roller, the hubs resting against the inclined ways A of the frame A, while the body of the roller is pressed by gravity against the top of the relief sensitized paper. The friction of the roller with the paper operates to rotate the same when the former is drawn toward the printing-frame a, and the friction of the hubs 5 upon the ways A offers the requisite resistance to such movement.

The take-up roll 25 consists in a heavy cylinder like the brake-roller 8 having a longitudinal notch 25', into which the end of the web to is wedged to secure itthereto, and the said roll tis sustained by the measuring-roll m in conjunction with the inclined ways A engaging hubs i at either end of the same.

The measuring-roll mis mounted in suitable bearings upon the frame A and operates when actuated by the ratchet device connected therewith to draw the web wof sensitized paper from the supply-roll s, over the guideroller 1", under the printing-frame a, over the guide-roller a", and around the said measuring-roll, as indicated in dotted lines in Fig. 1, and to rotate the take-up rollt by its friction therewith, thus winding upon the latter the web drawn from the supply-roll s. It will be observed that as the roll of paper increases upon the rollt the latter recedes upwardly from the measuring-roll along the way A but as the outer face of the said Way is made radial with relation to the measuring-roll m its weight acts upon the said roll at the same point regardless of the size the roll attains. The converse of this is true with regard to the action of the brake-roller for as the paper is drawn from the supply-roller and the size of the roll diminishes the weight of the roller continues to act in the same radial line and for the above reason.

In order to rotate the 1neasuring-roll intermittingly and uniformly for each cycle of the machine, the shaft m of the measuring-roll is provided with a spur-wheel m and a stud U is applied to the frame A adjacent thereto and provided with the loose ratchet and spur wheels o and r respectively, secured rigidly together and the latter meshing with the gear m A slotted arm at is also pivoted upon the stud 'u and provided with the pawl u to engage the ratchet-wheel v. A slotted crank 76 is applied to the main shaft S and connected by means of the sleeve a to the arm a by the rod q, having collars q secured adjustably thereon on either side of the sleeve M The sleeve 10 is secured adjustable radially upon the arm u by means of a bolt a passing through a hub upon the same and the slot in the arm, and the rod q is secured adjustably to the crank it in the same manner. It is obvious that the rotation of the crank operates to reciprocate the rod (1 so as to cause a similar motion in the pawl arm u, the distance between the collars q determining the fraction of a cycle of the machine in which the pawl-arm acts with a given radial adj ustment of the rod g. It is also evident that the reciprocation of the said pawl-arm operates to rotate the measuring-roll 772 through agiven are for each forward stroke of the same, which latter in its turn rotates the roll tsufficiently to take up that portion of the web drawn from the supply-roll by the measi'iring-roll, the character and extent of the motion of such members being determined by the various adjustments of the ratchet device already referred to. v

The switching device for controlling the electric lamps in the box Z2 consists in two adjacent but electrically independent springcontacts 2, interposed in the electric circuit m supplying the lamps, the same having opposed fiat faces in close proximity and being mounted in any convenient position near the main or power shaft S. A segmental plate y, divided into two flat sections having suitable hubs y and clamped together by the screw 21 is fixed upon the power-shaft adjacent to the said spring-contacts and suitably insulated therefrom. This contact-plate is rotated by the said shaft between the said springconfacts .2 to establish electrical connection intermittingly between the same, thus making and extinguishing the light in the box I) at the required periods in the cycle of the machine. By forming the plate y in two sections, as above described, the latter may be readily adjusted circumferentially upon each other in order to lengthen or shorten the connection established between the spring-contacts 2'. In Fig.1 the contact-plate y is omitted to avoid confusion with the other seg mental platesj upon the same shaft; but the construction and operation of the switching device are fully illustrated in Figs. 3 and 4.

In Fig. 1 I have shown attached to the frame of the machine a registering device Rof wellknown construction, which is actuated by a vibrating lever B, the same being commonly employed in registering the strokes of various reciprocating mechanisms. To actuate such device I mount a rock-shaft 0 upon the frame A above the tie-rod T, and upon its inner and outer ends I secure the laterally-projecting arms 0' and 0 respectively, extending in opposite directions, the arm 0' projecting toward the shaft S. Upon the said shaft is fixed the dog 0 in a line with the end of the inner arm 0', each rotation of the shaft thereby causing the reciprocation of the rock-shaft O and the corresponding actuation of the register R by means of the link 0 connecting the arm 0 with the lever R. The figure illustrates the machine just after the completion of the printing operation, the ratchet device making its forward stroke to actuate the measuring-roll m. The further rotation of the shaft S first causes the registry of the completion of a cycle of the machine and then finishes the feeding operation, the cushion-platen p having previously been withdrawn to permit the forward movement of the web 10. At the end of the forward stroke of the crankk, the cam j releases the depending arm of the bell-crank f, which, through the action of the counterbalanceweight W, presses the cushion'platen upward against the negative 91. The segmental com IIO tact plate 1 now operates to establish the current through the incandescent lamps in the box I), which causes the exposure of the negative and that portion of the web to undertheprinting-frame to its action. After the required period of exposure the current is broken in a similar manner, the camj withdraws the cushion-platen p by engagement with the bell-crankf, and the crank 7e again actuates the measuring-roll on, during which movement the registering device R is made to record another completed cycle of the machine.

I have referred to my machine herein as being adapted to print successively from a single negative, by whichexpression I mean a negative, whether upon an integral glassplate or composed of several smaller sections, from which a print may be made in a single operation.

In order to print from several independent negatives, it is first necessaryto combine them in a single one by securing each rigidly to the printing-frame, and it is in this sense that I have used the term single negative herein.

Having thus set forth my invention, what I claim herein, and desire to secure by Letters Patent, is
